Solution
At a given temperature, solubility is defined as the maximum amount of solute that can dissolve in a known quantity of solvent. For example, Sugar in water.
It is not required that the solute be liquid; it can exist in any state of matter, including solid, liquid, and gas.
The solubility of a solution is affected by a variety of factors.
So a substance's solubility is determined by its physical and chemical properties.
Temperature, pressure, and the forces between the particles all affect solubility.
A solution's solubility can be changed by varying its temperature.
We can increase a solute's solubility by increasing its temperature.
We know that water dissolves various solutes or sparingly soluble solid substances, which can be completely dissolved by raising the temperature to a higher level.
The solubility of gases decreases in polar solvent water with an increase in temperature. For example, a saturated solution of salt in water becomes unsaturated by increasing temperature. However, in the case of a gaseous substance, the solubility factor is inversely proportional to the temperature, meaning that as the temperature rises, gases expand and escape from their solvent.
The solubility of gases decreases in polar solvent water with an increase in temperature. As a result, increasing the temperature improves the solubility of solids and also liquids, but increasing the temperature decreases the solubility of any substance in gases form.
For example, the solubility of gases decreases in polar solvent water with an increase in temperature as;
